TOBACCO PIPE.

Application led September This invention relates to improvements in tobacco pipes. and more particularly to attachineiits therefor-` in important object of the invention is to provide a. pipe having a'swinging cover mounted thereon adapted topermitthe discharge of undesired matter therein.

A further object of thev invention is the provision of a pipe of this character having.

a hinged cover plate mounted at the lower extremity of a suitable chamber formed in the pipev for the collection of tobacco and moisture.

ri still further objectV of the invention is the provision of a pipe of this character having means for the collection and discharge of undesirable matter such as tobacco, ashes and moisture.

Other objects and advantages of this inventionwill be apparent during the course of the following' description. y

1n the drawings, wherein for the purpose ofv illustration is shown the`V preferred embodiments of my invention, the numeral 10 generallyfdesignates a commonV formfof tobacco pipe comprising ai bowl 11 and a stem 12 formed integralwith the bowl and extending at substantiallyI right angles to the ylower portion thereof. A mouthpiece 13 is tlireadedly or otherwise mountedu'pon the outer extremity of the stem 12, this mouth- 26, 1925. Serial N0. 58,790.

piece being commonly constructed lof rubber composition or ysimilar material.

In common usage, pipes of this character are provided with a longitudinal boreex` tending through the pipe stem and `form-ing a passage connecting with the bowl, the mouthpiece being provided with av similar bore adapted to align with thebore formed in' the stem. The smoke is usually drawn directly through this passage from the bowl, naturally carrying particles of tobacco Land moisture which obviously collect therein, through this bore and into the mouth of the smoker. 1n my improved pipe illustrated in the drawings, I provide a transversely ex tending bore 14 formed in the stem and extending from the lower portion thereof to within a short distance of the upper portion, this bore forming a chamber or receptacle adapted to prevent the passage of tobacco and collect the moisture which may gather in the pipe. The mouthpiece 13 is provided with the usual longitudinal borerdenoted by the numeral 15, while the stem 12 is provided with a pair of longitudinally extending bores 16 and 17.r The bore 16 extends from the interior or bowl of the pipe to the chamber 14, while the bore 17 extends fromthe chamber to the extremityl of the stem.` The bores as clearly shown in the drawings are preferably out of alignment, fthe forward bore 17 connecting with the chamber at a slightly elevated position in relation to vthe bore 16 in order to prevent passa e of matter .directly through the stem. This arrangement ofthe bores in the stem'enable's the user to readily draw through the "pipe, ybut causes the chamber formed in the stemto l Vbattle the matter drawn directly from the bowl of the pipe, this matter collecting in the chamber. Saliva 0r other matter lwhich may be deposited in the forward portion of the pipe stem and mouthpiece will naturally flow downwardly intov the' chamber and'be r-etained therein.

Referring more particularly lto the construction of the chamber or transverse bore formed inthe stem, I consider it desirable to line the lower portion of the chamber with a tube 18, this tubevbeingpreferably of metallic construction and secured within the chamber by indentations 19y orin any similar manner. The lower ked e of one side of the tube is provided with'sec'tions 20 adapt- Hed to form hinge members, the/purpose of which will be hereinafter explained. As it is desirable to enclose the lower portion of the chamber in a readily operable manner, I provide a cover plate 21, the lower face thereof being adapted to conform to the contour of the pipe stem. The upper side of the cover plate isof concave formation being provided about the periphery thereof wit-h an extension edge or `flange 22. A packing ring 23 is mounted on the upper portion of the flange 22'and is preferably constructed of rubber or like ,yieldable material adapted to permit the cover to close the lower extremity of the chamber in an air-tight manner. ris it is desirable that the cover plate fit flush 'with the lower portion of the pipe stem, the lining tube 18 does not extend entirely to the extremity of the chamber, thus forming a recess in which the cover plate and packingy ring snugly lit. The edge of the cover plate is providedy with a hinge member 2a adapted to align with the extension edges 2O formed 'on thelower portion of the tube 18, forming means by which the cover may be swung in an opener closed position. f l

In order that the cover may normally 'swing in an open position, I provide a spring member 25, one extension thereof passing through the hinge sections and forming the hinge pin and suitably fastened into the body of the stem as shown at 26. rllhe other extremity of the spring member is bent upwardly and twisted to form a coil 27 and extends over the central portion of the cover plate, thus having a tendency to force downwardly on the cover plate and normally retain same in an open position.

The cover plate is retained in the closed position by means of an ai'cuately bentV rod 28, the upper extremity of this rod being adapted incertain positions to engage an arcuate Igroove 29 formed in the lower portion'of the stem adjacent the chamber for this purpose. The other'v extremity of this rod is threadedly or otherwise secured to a concave cap 29V adapted to fit within a suitably formed recessv within the lower portion of the cover plate. rlhe lower' face yof the cap 29 is providedwith-a plurality of rib members 30 formed on the cap member and Aadapted to permit convenient rotation of the A Same.

has been eagerly sought.

In use, my improved pipe is designed to obviate the disagreeable feature in pipe smoking, namely, the passage of particles of tobacco through the stem and themixture of this tobacco with saliva, the resultant mass being drawn into the'iiioutli of the smoker. As it is well known to those familiar Lwith the art,` the assimilation of this matter is distasteful and-also often sickening tothe smoker andelimination thereof l have accomplished thisl in a comparatively simple yet readily conceivable manner, 'thel formation -the smoker drawingparticles of tobacco into the mouthpiece and mouth, these particles striking the walls of the chamber and collecting as residue at the bottom of the chainber. yllloisture collecting in the forward por# tion of the 'stem and mouthpiece willv naturally flow downwardly through the bores formed therein and also be deposited' in the chamber, the bowl of the pipe usually being in a lower position than the mouthpiece.

After the pipe has been smoked for a substantial length of time, the chamber may 'be readily emptied and the matter collected` therein emptied. This is accomplished by merely forcing the finger against thecap 29, the ribs formed thereon permitting the same to be readily rotated and swing the upper portion of the rod 28 out of engagement with the arcuate groove formed in the stem,

the spring 28 forcing the cover downwardly in an open position and permitting the undesirable matter collected in the chamber to be readily emptied therefrom. It isV obvious that this structure does not mar the appearance of thepipe nor make it necessary to provide cumbersome fixtures, the general structure of the pipe conforming very generally to the common form and being practically unnoticeable. t

In Figures 6, 7, 8, and 9 of the official drawingsI have shown a slightly modified form of closure for the lower end of the vertical bore ll. In this form the tube 18 terminates slightly above the lower face of the stem 12, so as to provide a shoulder 35.

4rlhe shoulder 85 is engaged by an annular enlarged portion 36 formed on the .disk

iio

plate 38 which has extending centrally f therethrough one extremity of a wire 39.

said extremity having a head lO'f'formedV thereon which engages under the plate 3 8 so as :to pivotally connectthe' closure member 37 to' the wire 89. The wire 89after heilig attached to the closure member extends towards the tube 18 slightly above the plate 38 `and is coiled, as at'lO, for providing means for swinging'the closure member outwardly when said closure member is released.

Aftervforming the coil 40 the Vwire extends upwardly, as at 4:1, engaging the interior of the tube 18` andbore 14 and is then looped V or turned back upon itself to provide a pair of parallel spaced strands Vof, wire.;vlIheV y extremity after forming the loop is' bentv CLC over the strand of wire 89 adjacent the coil so as to provide an elongated loop 42. ,Extending through the loop 42 is a small nail 43 or the like, which also extends through the tube 18 and into the stem l2, sa'id nail having an enlarged head 44' provided thereon for slidably retaining the elongated loop 42 against the interior of the tube i8 and interior of the bore 14.

Arranged to project slightly inwardly into the bore 14 at the lower portion thereof loe-v lowthe sleeve 18 is a pair of pins 45, which are adapted to be received in L-shapved grooves 46 formed in the periphery of the annular portion 3G ot' the closure member 37 'for holding the closure disk 37 in a closed position.

in this form of my invention, it` can be seen that when it is desired to open the lower end of the bore 14, the closure disk 37 is slightly turned by the operator engaging the saine with the thumb, said turning movement pern'iitting the L-shaped grooves 4G to be disengaged i'rom the pins 45, which will cause the closure member 37 to be swung outwardly by the coil 40 formed on the wire lt can be seen that when the coil 40 swings the closure member 37 that said Closure member and wire 39 will be moved downwardly, the loop 42 sliding upon the pin 48, thus swinging the closure member to a position which will permit ready access to the bore 14.

t is to be understood that the forms of my invention herewith shown and described are to be taken as the preferred examples of the same, and'that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention,V or the scope of the subjoined claims.

Having thus described my invention, I claim: f
